Mystoryboard and mypointanimation do not exist?

.xaml

<Canvas MouseLeftButtonDown="Handle_MouseDown"
Background="Gray" Width="600" Height="500">
<Canvas.Resources>
<storyboard x:name="myStoryboard">

<!-- The PointAnimation has a name so it can be accessed
from code. The To property is left out of the XAML
because the value of To is determined in code. -->
<PointAnimation
x:Name="myPointAnimation"
Storyboard.TargetProperty="Center"
Storyboard.TargetName="MyAnimatedEllipseGeometry"
Duration="0:0:2"/>

</Canvas.Resources>

<Path Fill="Blue">
<Path.Data>

<!-- Describes an ellipse. -->
<ellipsegeometry x:name="MyAnimatedEllipseGeometry"
="" center="200,100" radiusx="15" radiusy="15">
</Path.Data>
</Path>

</Canvas>


.cs
private void Handle_MouseDown(object sender, MouseButtonEventArgs e)
{
// Retrieve current mouse coordinates.
double newX = e.GetPosition(null).X;
double newY = e.GetPosition(null).Y;
Point myPoint = new Point();
myPoint.X = newX;
myPoint.Y = newY;
myPointAnimation.To = myPoint;
myStoryboard.Begin();
}

Both are define din .xaml, is that not enough?
